Answer:
58 m
Explanation:
You want the perimeter of the L-shaped figure shown.
Perimeter
The perimeter is the sum of the side lengths. Here, a couple of lengths are missing from the diagram, but that doesn't prevent us finding the perimeter.
Horizontal
The horizontal lengths at the top have the same total length as the length at the bottom marked 19 m. This means the sum of all of the horizontal lengths is ...
2 × 19 m = 38 m
Vertical
The vertical lengths at the right side have the same total length as the vertical length at the left side, marked 10 m. This means the sum of all of the vertical lengths is ...
2 × 10 m = 20 m
Total
The perimeter is the sum of the horizontal and vertical lengths:
P = 38 m + 20 m = 58 m
The perimeter of the figure is 58 m.
